EXIPICK

NAME

exipick - selectively display messages from an Exim queue

SYNOPSIS

exipick [<options>] [<criterion> [<criterion> ...]]

DESCRIPTION

exipick is a tool to display messages in an Exim queue. It is very similar to exiqgrep and is, in fact, a drop in replacement for exiqgrep. exipick allows you to select messages to be displayed using any piece of data stored in an Exim spool file. Matching messages can be displayed in a variety of formats.

QUICK START

Delete every frozen message from queue:
exipick -zi | xargs exim -Mrm

Show only messages which have not yet been virus scanned:
exipick '$received_protocol ne virus-scanned'

Show the count and total size of all messages which either originated from localhost or have a received protocol of 'local':
exipick --or --size --bpc \
'$sender_host_address eq 127.0.0.1' \
'$received_protocol eq local'

Display all messages received on the MSA port, ordered first by the sender's email domain and then by the size of the emails:
exipick --sort sender_address_domain,message_size \
'$received_port == 587'

Display only messages whose every recipient is in the example.com domain, also listing the IP address of the sending host:
exipick --show-vars sender_host_address \
'$each_recipients = example.com'

Same as above, but show values for all defined variables starting with sender_ and the number of recipients:
exipick --show-vars ^sender_,recipients_count \
'$each_recipients = example.com'

OPTIONS

--and

Display messages matching all criteria (default)

-b

Display messages in brief format (exiqgrep)

-bp

Display messages in standard mailq format (default)

-bpa

Same as -bp, show generated addresses also (exim)

-bpc

Show a count of matching messages (exim)

-bpr

Same as '-bp --unsorted' (exim)

-bpra

Same as '-bpa --unsorted' (exim)

-bpru

Same as '-bpu --unsorted' (exim)

-bpu

Same as -bp, but only show undelivered messages (exim)

-c

Show a count of matching messages (exiqgrep)

--caseful

Make operators involving '=' honor case

--charset

Override the default local character set for $header_ decoding

-f <regexp>

Same as '$sender_address =~ /<regexp>/' (exiqgrep). Note that this preserves the default case sensitivity of exiqgrep's interface.

--finput

Same as '--input-dir Finput'. 'Finput' is where exim copies frozen messages when compiled with SUPPORT_MOVE_FROZEN_MESSAGES.

--flatq

Use a single-line output format

--freeze <cache file>

Save queue information in an quickly retrievable format

--help

Display this output

-i

Display only the message IDs (exiqgrep)

--input-dir <inputname>

Set the name of the directory under the spool directory. By defaut this is ``input''. If this starts with '/', the value of --spool is ignored. See also --finput.

-l

Same as -bp (exiqgrep)

--not

Negate all tests.

-o <seconds>

Same as '$message_age > <seconds>' (exiqgrep)

--or

Display messages matching any criteria

-R

Same as --reverse (exiqgrep)

-r <regexp>

Same as '$recipients =~ /<regexp>/' (exiqgrep). Note that this preserves the default case sensitivity of exiqgrep's interface.

--random

Display messages in random order

--reverse

Display messages in reverse order

-s <string>

Same as '$shown_message_size eq <string>' (exiqgrep)

--spool <path>

Set the path to the exim spool to use. This value will have the argument to --input or 'input' appended, or be ignored if --input is a full path.

--show-rules

Show the internal representation of each criterion specified

--show-tests

Show the result of each criterion on each message

--show-vars <variable>[,<variable>...]

Show the value for <variable> for each displayed message. <variable> will be a regular expression if it begins with a circumflex.

--size

Show the total bytes used by each displayed message

--thaw <cache file>

Read queue information cached from a previous --freeze run

--sort <variable>[,<variable>...]

Display matching messages sorted according to <variable>

--unsorted

Do not apply any sorting to output

--version

Display the version of this command

-x

Same as '!$deliver_freeze' (exiqgrep)

-y

Same as '$message_age < <seconds>' (exiqgrep)

-z

Same as '$deliver_freeze' (exiqgrep)

CRITERIA

Exipick decides which messages to display by applying a test against each message. The rules take the general form of 'VARIABLEOPERATORVALUE'. For example, '$message_age > 60'. When exipick is deciding which messages to display, it checks the $message_age variable for each message. If a message's age is greater than 60, the message will be displayed. If the message's age is 60 or less seconds, it will not be displayed.

Multiple criteria can be used. The order they are specified does not matter. By default all criteria must evaluate to true for a message to be displayed. If the --or option is used, a message is displayed as long as any of the criteria evaluate to true.

See the VARIABLES and OPERATORS sections below for more details

OPERATORS

BOOLEAN

Boolean variables are checked simply by being true or false. There is no real operator except negation. Examples of valid boolean tests:
'$deliver_freeze'
'!$deliver_freeze'

The string operators are =, eq, ne, =~, and !~. With the exception of '=', the operators all match the functionality of the like-named perl operators. eq and ne match a string exactly. !~, =~, and = apply a perl regular expression to a string. The '=' operator behaves just like =~ but you are not required to place // around the regular expression. Examples of valid string tests:
'$received_protocol eq esmtp'
'$sender_address = example.com'
'$each_recipients =~ /^a[a-z]{2,3}@example.com$/'

NEGATION

There are many ways to negate tests, each having a reason for existing. Many tests can be negated using native operators. For instance, >1 is the opposite of <=1 and eq and ne are opposites. In addition, each individual test can be negated by adding a ! at the beginning of the test. For instance, '!$acl_m1 =~ /^DENY$/' is the same as '$acl_m1 !~ /^DENY$/'. Finally, every test can be specified by using the command line argument --not. This is functionally equivilant to adding a ! to the beginning of every test.

VARIABLES

With a few exceptions the available variables match Exim's internal expansion variables in both name and exact contents. There are a few notable additions and format deviations which are noted below. Although a brief explanation is offered below, Exim's spec.txt should be consulted for full details. It is important to remember that not every variable will be defined for every message. For example, $sender_host_port is not defined for messages not received from a remote host.

Internally, all variables are represented as strings, meaning any operator will work on any variable. This means that '$sender_host_name > 4' is a legal criterion, even if it does not produce meaningful results. Variables in the list below are marked with a 'type' to help in choosing which types of operators make sense to use.

TRUE if unqualified recipient addresses are permitted in header lines.

B + $allow_unqualified_sender

TRUE if unqualified sender addresses are permitted in header lines.

S . $authenticated_id

Optional saved information from authenticators, or the login name of the calling process for locally submitted messages.

S . $authenticated_sender

The value of AUTH= param for smtp messages, or a generated value from the calling processes login and qualify domain for locally submitted messages.

S . $bheader_*, $bh_*

Value of the header(s) with the same name with any RFC2047 words decoded if present. See section 11.5 of Exim's spec.txt for full details.

S + $bmi_verdicts

The verdict string provided by a Brightmail content scan

N . $body_linecount

The number of lines in the message's body.

N . $body_zerocount

The number of binary zero bytes in the message's body.

S + $data_path

N + $deliver_frozen_at

The epoch time at which message was frozen.

B + $dont_deliver

TRUE if, under normal circumstances, Exim will not try to deliver the message.

S + $each_recipients

This is a psuedo variable which allows you to apply a test against each address in $recipients individually. Whereas '$recipients =~ /@aol.com/' will match if any recipient address contains aol.com, '$each_recipients =~ /@aol.com$/' will only be true if every recipient matches that pattern. Note that this obeys --and or --or being set. Using it with --or is very similar to just matching against $recipients, but with the added benefit of being able to use anchors at the beginning and end of each recipient address.

S + $each_recipients_del

Like $each_recipients, but for $recipients_del

S + $each_recipients_undel

Like $each_recipients, but for $recipients_undel

B . $first_delivery

TRUE if the message has never been deferred.

S . $header_*, $h_*

This will always match the contents of the corresponding $bheader_* variable currently (the same behaviour Exim displays when iconv is not installed).

S + $header_path

The path to the header file's location in the filesystem.

B . $host_lookup_deferred

TRUE if there was an attempt to look up the host's name from its IP address, but an error occurred that during the attempt.

B . $host_lookup_failed

TRUE if there was an attempt to look up the host's name from its IP address, but the attempt returned a negative result.

B + $local_error_message

TRUE if the message is a locally-generated error message.

S . $local_scan_data

The text returned by the local_scan() function when a message is received.

B . $manually_thawed

TRUE when the message has been manually thawed.

N . $max_received_linelength

The number of bytes in the longest line that was received as part of the message, not counting line termination characters.

N . $message_age

The number of seconds since the message was received.

S # $message_body

The message's body. Unlike Exim's variable of the same name, this variable contains the entire message body. Newlines and nulls are replaced by spaces.

B + $message_body_missing

TRUE is a message's spool data file (-D file) is missing or unreadable.

N . $message_body_size

The size of the body in bytes.

S . $message_exim_id, $message_id

The unique message id that is used by Exim to identify the message. $message_id is deprecated as of Exim 4.53.

S . $message_headers

A concatenation of all the header lines except for lines added by routers or transports. RFC2047 decoding is performed

S . $message_headers_raw

N . $received_count

The number of Received: header lines in the message.

S . $received_protocol

The name of the protocol by which the message was received.

N . $received_time

The epoch time at which the message was received.

S # $recipients

The list of envelope recipients for a message. Unlike Exim's version, this variable always contains every recipient of the message. The recipients are separated by a comma and a space. See also $each_recipients.

N . $recipients_count

The number of envelope recipients for the message.

S + $recipients_del

The list of delivered envelope recipients for a message. This non-standard variable is in the same format as $recipients and contains the list of already-delivered recipients including any generated addresses. See also $each_recipients_del.

N + $recipients_del_count

The number of envelope recipients for the message which have already been delivered. Note that this is the count of original recipients to which the message has been delivered. It does not include generated addresses so it is possible that this number will be less than the number of addresses in the $recipients_del string.

TRUE if the message was locally generated.

B + $sender_set_untrusted

TRUE if the envelope sender of this message was set by an untrusted local caller.
